The Brits studied 8,170 men and women born in the year 1970. Participants took an IQ test at the ripe old age of 10. And 20 years later, they were asked whether they were vegetarians.

Most were not. But 366 said that they were. And higher IQ at age 10 was associated with an increased likelihood of being vegetarian at age 30.

The vegetarians were more likely to be female, more likely to be of a higher social class, and more likely to have gone further in their education. But even after adjustment for all of these factors, kids with high IQs were more likely to become adults who eschewed red meat. Hello Socrates, goodbye steak!
